中国实验快堆汽轮机组热力校核计算

Thermodynamic check calculation for the turboset of CEFR

CEFR是中国第一座快中子实验反应堆,三回路承担了将核岛热能转换为电能的重要功能。其汽轮机组自从安装调试以来,经历了三次辅助蒸汽冲转试验及40%P0工况下并网发电试验,但是其额定功率热力性能一直无法得到验证。本文通过热力校核计算,验证了机组额定功率下的做功能力并得出了其热经济性,对快堆全厂热平衡计算有着重要参考意义。

CEFR is the first sodium coolant fast reactor in China. The main function of the three loops is to transform the heat energy from the nuclear island to electricity energy. The turboset has completed three auxiliary steam impact tests and the grid- connected power generation test in 40- P0 working eondition after installed and commissioned, but its rated power thermodynamic performance cannot he demonstrated at all times. By thermodynamic check calculation, this paper demonstrates that its capacity at rated power and gets its thermal economics. It also provides significant reference for the whole plant thermal equilibrium calculation of CEFR.
